A dispersion component and a disc mill

Abstract

This utility model discloses a dispersion component and a disc mill. The dispersion component includes: a rotating shaft; a dispersion wheel disposed on the rotating shaft and capable of rotating synchronously with the shaft; and a wear-resistant part disposed on the outer contour edge of the dispersion wheel. The wear-resistant part is made of ceramic material and is used to contact the material when the rotating shaft rotates. This utility model disperses the material by providing a wear-resistant part made of ceramic material on the outer contour edge of the dispersion wheel, allowing the wear-resistant part to contact the material. Because ceramic material has high wear resistance, it is not easily worn during contact with the material. Even if wear occurs and ceramic powder is generated, its impact on product quality is relatively small. Compared to using all metal materials, it is less prone to wear and can improve product quality.

Description

Technical Field

[0001] This utility model relates to the technical field of material crushing equipment, and in particular to a dispersion component and a disc mill. Background Technology

[0002] Disc mills are specifically designed for the production of ultrafine powders with strict requirements on particle size distribution. They can simultaneously achieve material crushing (deagglomeration), drying, and surface chemical treatment of the powder. They can also achieve the same effect on liquid materials or filter cakes after pressure filtration. A disc mill consists of a shell, disc assemblies, and a dispersing assembly. The shell defines a working chamber. After entering the working chamber, the material passes sequentially through the dispersing assembly and the disc assemblies. The dispersing wheel of the dispersing assembly first breaks up large pieces of material, and then the disc assemblies perform a more refined crushing process. Existing dispersing assemblies use metal dispersing wheels, which are prone to wear after long-term use. The metal debris generated by this wear can mix into the material, affecting the quality of the final product, especially for materials that cannot tolerate metal impurities. Utility Model Content

[0019] According to some embodiments of the present invention, multiple dispersing wheels are spaced apart along the axial direction of the rotating shaft, and the multiple dispersing wheels are staggered along the circumferential direction of the rotating shaft.

[0020] According to some embodiments of the present invention, a connecting sleeve is coaxially fixedly sleeved on the rotating shaft, and mounting surfaces are defined on opposite sides of the connecting sleeve in the axial direction.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Disc mills typically consist of a shell, disc assemblies, and a dispersing assembly. The shell defines a working chamber. After entering the working chamber, the material passes sequentially through the dispersing assembly and the disc assembly. The dispersing wheel of the dispersing assembly first breaks up large pieces of material, and then the disc assembly performs a more refined crushing process. However, the dispersing wheels in existing dispersing assemblies are prone to wear and have a short service life, requiring regular maintenance and replacement, which affects the equipment's operating efficiency.

[0039] Therefore, this utility model proposes a dispersion component and a disc mill, which can effectively improve the above-mentioned problems.

[0040] The dispersion component and disc mill according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] Reference Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a dispersion component, which includes a rotating shaft 100, a dispersion wheel 200, and a wear-resistant part 300.

[0042] The rotating shaft 100 is rotatably mounted; the dispersing wheel 200 is mounted on the rotating shaft 100 and rotates synchronously with the rotating shaft 100; a wear-resistant part 300 is mounted on the outer contour edge of the dispersing wheel 200, and the wear-resistant part 300 is made of ceramic material. The wear-resistant part 300 is used to contact the material when the rotating shaft 100 rotates to disperse the material. Clearly, the wear-resistant part 300 is fixed to the dispersing wheel 200.

[0043] The dispersion component of this utility model disperses the material by providing a wear-resistant part 300 made of ceramic material on the outer contour edge of the dispersion wheel 200. The wear-resistant part 300 contacts the material, thereby dispersing the material. Since ceramic material has high wear resistance, it is not easy to wear during contact with the material. Even if wear occurs and ceramic powder is generated, its impact on product quality is relatively small. Compared with using all metal materials, it is not easy to wear and can improve product quality.

[0044] This allows the dispersing wheel 200 to have a longer service life and extends the equipment's maintenance cycle.

[0045] Based on the above embodiments, it is conceivable that the dispersion wheel 200 can be made of metal material. The metal part of the dispersion wheel 200 can withstand high impact force and complex stress, avoiding the risk of brittle fracture of pure ceramic. The ductility of metal is more suitable for bearing long-term alternating loads, while the wear-resistant part 300 made of ceramic plays a wear-resistant role. The combination of the two can take into account both cost and mechanical performance.

[0046] Based on the above embodiments, it is conceivable that the wear-resistant part 300 can be made of one of the following materials: alumina ceramic, zirconia ceramic, and silicon carbide ceramic. Of course, other ceramic materials can also be used, which will not be listed here. The specific material can be selected according to the actual application requirements.

[0047] Reference Figure 1 As shown, in some embodiments of this utility model, the wear-resistant part 300 is bonded to the dispersion wheel 200, which is convenient for installation.

[0048] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the wear-resistant part 300 is bonded to the dispersing wheel 200. The wear-resistant part 300 is provided with a T-groove 301 on the side of the rotating shaft 100 along the radial direction. The T-groove 301 is provided through and extends perpendicular to the axial direction of the rotating shaft 100, that is, the two ends of the T-groove 301 are open in the extending direction. The T-groove 301 is used for the outer contour edge of the dispersing wheel 200 to be inserted. Along the axial direction of the rotating shaft 100, anti-detachment blocks 210 are fixed on opposite sides of the dispersing wheel 200. The anti-detachment blocks 210 are inserted into the T-groove 301 to limit the displacement of the wear-resistant part 300 away from the rotating shaft 100 along the radial direction of the rotating shaft 100, improve the connection stability between the wear-resistant part 300 and the dispersing wheel 200 during the rotation of the rotating shaft 100, and prevent the wear-resistant part 300 from detaching from the dispersing wheel 200 under the action of centrifugal force.

[0049] Based on the above embodiments, it is conceivable that the anti-detachment block 210 can also be made of metal material, and the anti-detachment block 210 can be connected to the dispersing wheel 200 in one of the following forms: welding, bonding, fastener connection, or integral molding. In addition, to improve the adhesion, the wear-resistant part 300 can be bonded to both the dispersing wheel 200 and the anti-detachment block 210 simultaneously.

[0050] Based on the above embodiments, it is conceivable that, in order to facilitate the installation of the wear-resistant part 300, the T-slot 301 can be set as a straight groove, that is, the T-slot 301 extends in a straight direction.

[0051] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, the outer contour edge of the dispersing wheel 200 has a first side 201 and a second side 202. The dispersing wheel 200 is provided with an anti-detachment block 210 on the first side 201. Along the rotation direction of the rotating shaft 100, the first side 201 and the second side 202 are arranged opposite to each other, and the first side 201 is located in front of the second side 202. At least one set of wear-resistant parts 300 is provided, and at least one set of wear-resistant parts 300 is provided on the first side 201. Obviously, since the first side 201 is located in front of the second side 202 along the rotation direction of the rotating shaft 100, when the rotating shaft 100 rotates, the material will preferentially contact and move along the wear-resistant part 300 of the first side 201 under the action of centrifugal force, thereby dispersing the material through the wear-resistant part 300.

[0052] It is understood that at least one set of wear-resistant parts 300 provided corresponding to the first side 201 includes multiple wear-resistant parts 300 arranged along the length direction of the first side 201. In this way, the size of a single wear-resistant part 300 can be reduced, and when the wear-resistant part 300 is damaged, the whole replacement can be avoided, thus reducing maintenance costs. Obviously, the wear-resistant part 300 can be set as a block structure.

[0053] It is understood that the dispersing wheel 200 is provided with at least two anti-detachment blocks 210 on the first side 201, and at least one anti-detachment block 210 is provided on each of the opposite sides of the first side 201 along the axial direction of the rotating shaft 100.

[0054] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the outer contour edge of the dispersing wheel 200 also has a third side 203, the two ends of the third side 203 are respectively connected to the first side 201 and the second side 202, and the dispersing wheel 200 is provided with an anti-detachment block 210 on the third side 203; wherein, at least two sets of wear-resistant parts 300 are provided, and at least one set of wear-resistant parts 300 is provided on the third side 203, so as to increase the contact area between the wear-resistant parts 300 and the material and improve the effect of dispersing the material.

[0055] Similarly, at least one set of wear-resistant parts 300 provided corresponding to the third side 203 includes a plurality of wear-resistant parts 300 arranged along the length direction of the third side 203; in addition, the dispersion wheel 200 is also provided with at least two anti-detachment blocks 210 at the third side 203, and at least one anti-detachment block 210 is provided on each of the opposite sides of the third side 203 along the axial direction of the rotating shaft 100.

[0056] Based on the above embodiments, in some specific embodiments, such as Figure 1 and Figure 2As shown, multiple wear-resistant parts 300 at the first side 201 abut against each other in sequence, and multiple wear-resistant parts 300 at the third side 203 abut against each other in sequence. Adjacent wear-resistant parts 300 of adjacent first side 201 and third side 203 abut against each other.

[0057] Reference Figure 2 As shown, in some embodiments of this utility model, the first side 201 and the third side 203 are both straight sides to facilitate the installation of the wear-resistant part 300.

[0058] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the dispersing wheel 200 includes two wing plates, which are symmetrically distributed with respect to the center of the rotating shaft 100. The outer contour edges of the two wing plates each have a first side 201, a second side 202, and a third side 203. The first side 201 and the third side 203 of the two wing plates are provided with wear-resistant parts 300. By providing two wing plates that are symmetrically distributed with respect to the center of the rotating shaft 100, the dispersing effect of the material can be improved, thereby improving the crushing quality of the subsequent material.

[0059] Based on the above embodiments, it is conceivable that the two wing plates of the dispersion wheel 200 can be configured as an integral structure to provide sufficient structural strength.

[0060] Based on the above embodiments, it is conceivable that, in order to make the force distribution wheel 200 more uniform, the first side 201 and the second side 202 of the same wing plate can be symmetrically distributed about the perpendicular line of the third side 203 (which passes through the midpoint of the third side 203). The length direction of the third side 203 is perpendicular to the radial direction of the rotating shaft 100.

[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, multiple dispersing wheels 200 are arranged at intervals along the axial direction of the rotating shaft 100, and the multiple dispersing wheels 200 are staggered along the circumference of the rotating shaft 100. This arrangement can further improve the dispersing effect on materials.

[0062] In one specific embodiment, two dispersing wheels 200 are provided, and the two dispersing wheels 200 are distributed at a 90-degree angle to each other in the circumferential direction of the rotating shaft 100.

[0063] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, a connecting sleeve 110 is coaxially fixedly sleeved on the rotating shaft 100. Mounting surfaces 111 are defined on opposite sides of the axial direction of the connecting sleeve 110, and the mounting surfaces 111 are perpendicular to the axial direction of the connecting sleeve 110. A dispersing wheel 200 has a central hole 204 and is sleeved on the connecting sleeve 110 through the central hole 204. Two dispersing wheels 200 are provided, and the two dispersing wheels 200 are respectively fixed to the mounting surfaces 111 on opposite sides of the axial direction of the connecting sleeve 110 by fasteners. This arrangement facilitates the disassembly and assembly of the dispersing wheels 200, improving maintenance convenience. Obviously, the fasteners can be screws, and multiple screws can be provided, evenly spaced along the circumference of the rotating shaft 100 to improve the uniformity of force transmission.

[0064] Based on the above embodiments, it is conceivable that the connecting sleeve 110 can be connected to the rotating shaft 100 in various forms; for example, the connecting sleeve 110 can be directly locked to the rotating shaft 100 by fastening screws; or, for another example, a flat key and a keyway can be provided between the connecting sleeve 110 and the rotating shaft 100 to achieve circumferential relative positioning between the two, while the axial relative positioning between the connecting sleeve 110 and the rotating shaft 100 can be achieved by the bushing and the limiting structures at both ends of the rotating shaft (such as expansion sleeves, round nuts, etc.); the above structural forms are all conventional settings, so this embodiment will not describe them in detail.

[0065] This utility model embodiment also proposes a disc mill, which includes the dispersion component of the first aspect embodiment described above.

[0066] In some specific embodiments, such as Figure 3 As shown, the disc mill also includes a housing 400, a disc assembly 500, and a drive mechanism 600. The housing 400 defines a working chamber, with a feed inlet at the bottom and a discharge outlet at the top. A dispersing assembly is disposed within the working chamber, wherein a rotating shaft 100 is rotatably disposed within the housing 400 and is connected to the drive mechanism 600 for transmission, and a dispersing wheel 200 is located within the working chamber. The disc assembly 500 is connected to the rotating shaft 100 and can rotate synchronously with the rotating shaft 100. The disc assembly 500 is located within the working chamber and above the dispersing wheel 200. The housing 400, disc assembly 500, and drive mechanism 600 are all conventionally configured, and this embodiment does not make any improvements to them, so they will not be described in detail here.

[0067] It should be noted that since the disc mill can adopt all the technical solutions of the dispersion component of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be elaborated here.

[0069] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
